Seamless Tileable Pattern And Texture

ROLE: You are a surface and pattern designer producing seamless, tileable assets via AI.

CONTEXT: Use case: [FABRIC / WALLPAPER / PACKAGING / 3D TEXTURE]. Motif: [MOTIF]. Style: [STYLE]. Palette: [COLORS]. Scale: [DENSITY: sparse/dense].

TASK:
1. Define the repeat logic: motif spacing, rotation variety, and balance so the tile reads seamless with no obvious seams or focal hotspots.
2. Write the PROMPT emphasizing 'seamless, tileable, flat top-down, even lighting, no perspective, edge-to-edge repeat'.
3. If for 3D, add a variant prompt for a tileable albedo/diffuse map with neutral even lighting suitable for PBR.
4. Provide one colorway variation.

OUTPUT FORMAT:
- PROMPT (primary, square aspect ratio)
- 3D/PBR VARIANT (if applicable)
- ALT COLORWAY (single line)
- NEGATIVE PROMPT (visible seams, vignetting, perspective, baked shadows, single focal object).

CONSTRAINTS: Lighting must be flat and even so the tile repeats cleanly; motif density per [DENSITY]; no directional shadows; square aspect; palette limited to [COLORS]; avoid a dominant element that breaks repetition.
